This part of IEC 62580@ which is a Technical Specification@ specifies the on-board video surveillance/CCTV system functionality and requirement for the purpose of interoperability between components of on-board video surveillance/CCTV systems in the same vehicle and subsystems in different vehicles of the same train@ which means two levels of interoperability are considered@ one is interoperability between components and another is between subsystems. This specification gives guidelines for: ? system breakdown structure of the on-board video surveillance/CCTV system; ? function breakdown structure of the on-board video surveillance/CCTV system@ and ? requirement of the on-board video surveillance/CCTV system. This specification is applicable to any type of train@ for example open trains@ multiple unit trains and closed trains. As illustrated in Figure 1@ this part of IEC 62580 provides video surveillance/CCTV services of monitoring@ recording and retrieval of data@ etc. This specification follows the general OMTS requirement defined in IEC 62580-1. The communication network of on-board video surveillance/CCTV system is based on the network defined by the IEC 61375 series@ in which IEC 61375-2-5 and IEC 61375-3-4 define communication between and within consists@ respectively@ IEC 61375-2-3 lays out the communication profile for the backbone which is used for the train coupling@ and IEC 61375-2-61 provides the support for the communication between on-board system and ground wayside infrastructures. The general system requirement of on-board video surveillance/CCTV system is developed based on IEC 62676 series with supplementing the special requirement for railway application. For interoperability implementation between components of system and subsystems@ this specification makes reference to IEC 62676-2-3@ which specifies a compliant IP video protocol and interface based on Web services. Special requirements for railway@ such as device discovery between consists and within a consist@ as well as network compliant to the IEC 61375 series are also defined here. In addition@ IEC 62676-4 gives recommendations and requirements for the selection@ planning@ installation@ commissioning@ maintaining and testing for use in security applications. Finally@ the requirement of exported data of on-board video surveillance/CCTV system is compliant with ISO 22311 if system is for security purpose.
